What to know

For the Manx Noir, Mercier Prototype chooses a stealthier direction than the white-dial version. A black ceramic dial is paired with a polished black PVD steel case, and twin recessed registers display the day of the week and the month. Luminous markers and hands create small islands of light, while the date window at six completes the calendar layout.

A three-quarter studio view shows the 42 mm case's strong lugs and the two calendar adjusters. It measures 51 mm from lug to lug, carries a domed sapphire crystal and is rated to 100 metres water resistance. The visible Miyota 9122 calibre drives the display mechanically and provides a quoted reserve of about 42 hours.

The Noir is one of two Manx colourways sharing a total individually numbered run of 200 watches. At $795, preorders are open with a shipping target of October 31, 2026. The watch is already publicly revealed; the near-term milestone is customer delivery, not an as-yet-secret announcement.
